[virtual]

This method is called by the GeomDrawingArea.

Here, derived classes should implement the drawing code.

Parameters:

context

the drawing context

Implements fawkes::GeomDrawer.

void fawkes::DrawingManipulator::get_color	(	float &	r,
		float &	g,
		float &	b
	)			const

Get the color.

Parameters:

	r	reference to a variable where the R value of the current color is written to
	g	reference to a variable where the G value of the current color is written to
	b	reference to a variable where the B value of the current color is written to

void fawkes::DrawingManipulator::integrate

(

const DrawingManipulator *

m

)

Integrates the parameters of another manipulator.

If a certain field in this manipulator is not set it is assigned the respective value from the specified manipualator.

Parameters:

m
